CLIProxyAPI Transform Your AI Subscriptions into Universal API Endpoints
CLIProxyAPI: Transform Your AI Subscriptions into Universal API Endpoints
Section titled “CLIProxyAPI: Transform Your AI Subscriptions into Universal API Endpoints”Introduction
Section titled “Introduction”In the rapidly evolving landscape of AI coding tools, developers often face a fragmentation problem: premium subscriptions are locked behind OAuth authentication, while many tools and SDKs expect standard API keys. CLIProxyAPI elegantly solves this bridge by converting OAuth-based AI services into universal API endpoints.
What is CLIProxyAPI?
Section titled “What is CLIProxyAPI?”CLIProxyAPI is an open-source proxy server written in Go that wraps multiple AI CLI tools and exposes them through standardized API interfaces. It transforms your existing AI subscriptions into OpenAI/Gemini/Claude-compatible APIs, eliminating the need for separate API keys.

Key Features and Highlights
Section titled “Key Features and Highlights”1. Multi-Provider OAuth Integration
Section titled “1. Multi-Provider OAuth Integration”CLIProxyAPI supports OAuth authentication for leading AI services:
- Claude Code - Anthropic’s Claude models via OAuth
- ChatGPT / OpenAI Codex - GPT series models
- Gemini CLI - Google’s Gemini models
- Qwen Code - Alibaba’s Qwen models
- iFlow - Additional AI service support
- Antigravity - Alternative AI provider
2. Universal API Compatibility
Section titled “2. Universal API Compatibility”The proxy provides standardized endpoints compatible with:
- OpenAI API format
- Gemini API format
- Claude API format
- Codex API format
This means your existing OpenAI SDK code works without modification—just change the base URL.
3. Advanced Account Management
Section titled “3. Advanced Account Management”- Multi-account support with round-robin load balancing
- Hot reload configuration changes take effect without restart
- OAuth session management with automatic token refresh
- Model mapping for intelligent fallback (e.g.,
claude-opus-4.5→claude-sonnet-4)
4. Comprehensive Feature Set
Section titled “4. Comprehensive Feature Set”- Streaming and non-streaming responses
- Function calling / tools support
- Multimodal input (text and images)
- Management API for runtime configuration
- Reusable Go SDK for embedding
- Docker containerization support
Prerequisites, Installation and Configuration
Section titled “Prerequisites, Installation and Configuration”System Requirements
Section titled “System Requirements”- Go 1.21+ (for building from source)
- Docker (optional, for containerized deployment)
- Valid subscriptions for supported AI services
Installation Methods
Section titled “Installation Methods”Method 1: Build from Source
Section titled “Method 1: Build from Source”git clone https://github.com/router-for-me/CLIProxyAPI.gitcd CLIProxyAPIgo build -o cliproxyapi cmd/server/main.go./cliproxyapiMethod 2: Docker Deployment
Section titled “Method 2: Docker Deployment”docker run -d -p 8080:8080 router-for-me/cliproxyapi:latestMethod 3: Pre-built Binaries
Section titled “Method 3: Pre-built Binaries”Download from the Releases page (393 releases available).
Quick Configuration
Section titled “Quick Configuration”- Configure OAuth Providers
Edit the configuration file to add your OAuth accounts:
providers: claude: type: oauth accounts: - email: "your@email.com" # OAuth flow will prompt for authentication
gemini: type: oauth accounts: - email: "your@gmail.com"
openai: type: oauth accounts: - email: "your@outlook.com"- Start the Server
./cliproxyapi --config config.yaml- Use Standard OpenAI SDK
from openai import OpenAI
client = OpenAI( base_url="http://localhost:8080/v1", api_key="any-key-ignored" # OAuth handles auth)
response = client.chat.completions.create( model="claude-opus-4.5", messages=[{"role": "user", "content": "Hello!"}])Recommended Scenarios and Best Practices
Section titled “Recommended Scenarios and Best Practices”Use Case 1: AI Coding Tool Integration
Section titled “Use Case 1: AI Coding Tool Integration”Use your Claude Code or ChatGPT subscription with tools that only support API keys:
- Claude Code desktop app
- Cline VS Code extension
- Roo Code assistant
- Continue.dev autopilot
Use Case 2: Multi-Account Load Balancing
Section titled “Use Case 2: Multi-Account Load Balancing”Distribute requests across multiple accounts to maximize usage limits:
load_balancing: strategy: round_robin accounts: - account1@example.com - account2@example.com - account3@example.comUse Case 3: Cost Optimization
Section titled “Use Case 3: Cost Optimization”Leverage free-tier subscriptions from multiple providers:
- Google Gemini (free tier available)
- Claude Code subscription
- OpenAI ChatGPT Plus
Best Practices
Section titled “Best Practices”- Security First: Management endpoints are localhost-only by design
- Model Fallback: Configure intelligent model mapping for availability
- Monitor Usage: Use the Management API to track account quotas
- Hot Reload: Modify configuration without service interruption

Precautions, FAQ and Troubleshooting
Section titled “Precautions, FAQ and Troubleshooting”Common Issues
Section titled “Common Issues”Q: OAuth token expires frequently
A: CLIProxyAPI handles automatic token refresh. Ensure your OAuth credentials are valid and check system time synchronization.
Q: Model not available
A: Use model mapping to route unavailable models to alternatives:
model_mappings: claude-opus-4.5: claude-sonnet-4Q: Rate limiting errors
A: Enable multi-account load balancing to distribute requests across accounts.
Security Considerations
Section titled “Security Considerations”- Management API endpoints bind to localhost only
- OAuth tokens are stored securely
- Never expose your proxy to public internet without authentication
- Regular audit logs track all API requests
Troubleshooting Tips
Section titled “Troubleshooting Tips”- Check logs:
tail -f cliproxyapi.log - Verify OAuth sessions via Management API
- Test with simple curl command first
- Ensure firewall allows localhost communication
